And as Jeff said - Amigas flash the power LED. The flash is between low
and high intensity, and it's actually an indication of the status of the
audio filter :&) IIRC, bright is off and dimmer is on. And yes, it flashes
before you get a Guru Meditation (kickstart 1.3 and below) or Software
Failure (kickstart 2+). Gives you a chance to press right mouse button and
fire up ROMwhack :&)
